I have an interesting anecdote to relate: Several years ago a group of amateur Greek chess players came up with a game we called "anti-chess". The idea was quite simple: if you got your opponent to take your king you won. The basic simplifying rule was that if any material was offered to be taken you had to take it - if several pieces could be taken at certain move you could choose among the alternatives. We played anti-chess for more than a year and had developed several scenarios where white lost if he played a set of first moves. However, we had not "solved" the problem of anti-chess. At an international tournament some Greek players showed this game of anti-chess to some Russians. We found out months later that "anti-chess" had been solved: white moves first, black always wins! Granted, anti-chess is not as elaborate as chess and the rule about having to capture material really limits choice and renders a lesser probability tree, however, the solution was anything but trivial. My experience with antichess makes me believe that chess is "solvable": the question of whether it is "practically solvable", however, is a different matter. Peter Vafeades
